What else can I help you with?
Is rice an element or a compound?
Neither; rice is a mixture of many compounds.
Does burning rice leave ashes?
Rice is made out of many carbohydrates. Therefore, in combustion, a residue of amorphous carbon is left.
What is the carbon content of major cereal crops?
The carbon content of major cereal crops is forty percent. This is applicable to dry content of the cereals. Carbon happens to be the biggest content.
How do you tell if something is a carbohydrate?
Carbohydrates are molecules that are made up of carbon, hydrogen, and oxygen. Foods that are high in carbohydrates include bread, pasta, rice, fruits, and vegetables. You can check the nutrition label to see the amount of carbohydrates present in a food item.
How we separate rice and water?
Rice can be separated from water by using a strainer or a colander. Simply pour the rice and water mixture into the strainer, and the water will drain out, leaving the rice behind.

Does burning rice leave ashes?
Rice is made out of many carbohydrates. Therefore, in combustion, a residue of amorphous carbon is left.
Is rice a c3 plant?
Yes, rice is a C3 plant. This means that it follows the C3 photosynthetic pathway, where the first chemical compound produced during photosynthesis is a three-carbon compound called 3-phosphoglycerate.
What are the changes in rice during th e fermentation of rice wine?
During the fermentation of rice wine, starches in the rice are converted into sugars by enzymes produced by mold, typically Aspergillus oryzae. Yeast then ferments these sugars into alcohol and carbon dioxide. This process also leads to the development of various flavors and aromas, altering the rice's original characteristics. Additionally, the texture of the rice may change, becoming softer as the fermentation progresses.
How does energy pass from the sun to the rice?
It happens by photosynthesis, in which carbon dioxide from the air is separated out into carbon, which is used to make the rice, and oxygen, which is mostly dumped into the atmosphere. Separating the carbon and the oxygen needs energy to break the chemical bonds between the atoms. That energy is recovered when the carbon is burned with oxygen, but that produces carbon dioxide as well, approximately as much as was absorbed in the first place.
What is the carbon content of major cereal crops?
The carbon content of major cereal crops is forty percent. This is applicable to dry content of the cereals. Carbon happens to be the biggest content.
Where does methane and carbon dioxide released in the air come from?
Methane comes from poor agricultural practices in cattle and pig farming and also from rice paddy fields. Carbon dioxide comes from the burning of fossil fuels (coal, oil and natural gas).
What is the carbon footprint of rice farming?
When rice grows it produces methane (through anaeorbic fermentation) In fact scientists believe that around 6-29% of the worlds annual methane emmissions are caused by rice farming. Keep in mind that rice farming must expand rapidly to keep up with the worlds growing need for it.
What is a C3 and C4 or CAM organisms?
C3, C4, and CAM are different photosynthetic pathways used by plants to fix carbon dioxide. C3 plants, such as wheat and rice, use the Calvin cycle to fix carbon dioxide. C4 plants, like corn and sugarcane, use a different enzyme to fix carbon dioxide and are more efficient in hot and dry conditions. CAM plants, such as cacti and pineapple, open their stomata at night and fix carbon dioxide into organic acids to use during the day.
